Abstract
AbstractDiverticular disease affects ∼5–10% people worldwide, yet the indications for elective colectomy in uncomplicated diverticulitis are unclear. As there is no strong scientific evidence regarding histology in diverticular disease, the primary outcome of the study was to analyze the degree of inflammation of colonic wall in patients that underwent elective colectomy for uncomplicated diverticulitis and to retrospectively assess the correlation between patient clinical history and pathological features of surgical specimens in order to find some predictive factors that may be strictly correlated with histology. An observational retrospective study was conducted. Patients undergoing elective colectomy for uncomplicated diverticulitis between January 2014 and January 2016 in an academic medical center were collected. The majority of patients (46.2%) had previously encountered one episode of acute diverticulitis prior to colectomy, while 21.5% and 10.8% had experienced two and three or more prior episodes respectively. Most patients had recurrent or chronic abdominal pain in the left iliac fossa (66.2%) for diverticular disease and a large proportion also experienced constipation (40.0%). Diverticulitis was identified pathologically as being “mild” in 44.6% patients and “severe” in 55.4% patients. The mean age was significantly lower in patients with severe diverticulitis (56.7 years) than in patients with mild diverticulitis (67.0 years). 71.9% of males had severe diverticulitis compared to 39.4% of females. Males have a 3.9 times higher risk of histological severe diverticulitis than females (OR = 3.932; 1.390–11.122; p = 0.008). Multivariate logistic regression analysis confirmed that age and gender were independent factors associated with histological diagnosis. Single-institution data and retrospective design were main limitations of this study. Age and gender are independent factors associated with severity inflammation index derived at histological analysis and they could be translated to clinical practice to better categorize patients with uncomplicated diverticulitis at the bedside.
